Hello everyone. I just don't get this . This seems very basic but I have problems to find a answer to this. I know augmented matrices and gaussian elimination.
Ok once again Ax = b
Okay I get the augmented matrix form. But how can I do this "backwards"
A is 2x2 matrix , and
b = Null vector
if A was [a,b;c,d] then I came up with 3c + 3d = 0 and then set c =1 ,d=-1
This didn't function
At the moment I am incapable of coming up with a matrix which certain vectors are in the kernel or image. I can't make a matrix which needs to have certain solutions.
